About this study
Official title: The Effect of Exercise Rehabilitation Regimes in Combination With Changes in Dialysis Procedures in Aspects Related to Quality of Life and Health in End Stage Renal Disease Patients
Despite the tremendous advances in dialysis technology, hemodialysis (HD) is a significant challenge for dialysis patients and quality of their lives[2]. Research has shown for years that dialysate fluid temperature and especially the typical dialysis (TD) temperature at (37°C) are complicated by hemodynamic instability which leading to an increased risk of heat-induced hypotension causing patient discomfort and increased mortality.
Cold dialysis (CD) is defined as the reduction of dialysis fluid temperature to 35-36°C, approximately 1°C below the typical dialysate temperature which ranges between 37-38°C. A number of studies have reported beneficial effects of CD on maintaining hemodynamic stability, minimizes hypotension and exerts a protective effect over major organs including the heart and brain. In addition, current evidence showed the protective effect of CD in cardiac performance during the dialysis session. As the investigators know until today cardiovascular mortality is an important issue for nephrologists that care for ESRD patients, however, many other benefits have been observed on patients' overall health and quality of life levels by used of CD.

The above-mentioned benefits of CD in the hemodynamic stability and the general quality of life of the patients are highlighted even further due to the ever-increasing adoption of intradialytic exercise programs. It has been well established that intradialytic exercise leads to benefits of physiological, functional, and psychological deterioration, which commonly accrues as a consequence of biological aging, catabolic illness, and a sedentary lifestyle, factors that may all contribute to the progressive decline of vitality and quality of life commonly observed in ESRD patients.
However, despite a strong rationale for the implementation of intradialytic exercise programs and the aforementioned benefits of CD, the separate and combined effects of these protocols in aspects related to quality of life and health in ESRD patients have not been investigated to date.
The aim of the current clinical study was to assess the effect of exercise rehabilitation regimes in combination with changes in dialysate temperature in aspects related to quality of life and health in end-stage renal disease patients receiving hemodialysis.
Read the detailed description
The primary aim of the clinical study was to investigate the combined effect of cold dialysis and aerobic exercise in aspects related to health. More specific:
- To investigate the thermoregulatory responses of hemodialysis patients under four different hemodialysis protocols.
- To assess the changes in muscular architecture and functional capacity in dialysis patients after 7 months of intradialytic exercise training.
- To assess the impact on insulin sensitivity and glucose disposal.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cold DialysisProcedure or surgery
Dialysate temperature reduced to 35oC for a period of 7 months.
Typical DialysisProcedure or surgery
Dialysate temperature is set at 37oC for a period of 7 months
ExerciseProcedure or surgery
Aerobic Intradialytic exercise training
| Study group | Role | What they receive |
|---|---|---|
| Standard Dialysis | Placebo comparator | Patients participated in a 7 months exercise trials receiving standard dialysis (at 37oC) Receives: Procedure: Typical Dialysis; Procedure: Exercise |
| Cold Dialysis | Experimental | Patients participated in a 7 months exercise trials receiving cold dialysis (at 35oC) Receives: Procedure: Cold Dialysis; Procedure: Exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Body Heat Storage
Body Heat storage will be assessed during the 4 hours of dialysis under the two main conditions. Body Heat Storage is calculated in Watt
Measured: Changes from baseline at 7 months
Change in Insulin Resistance
Insulin resistances will be assessed by an Oral Glucose Tolerance Test using the OGIS index
Measured: Changes from baseline at 7 months
Change in Muscle Size
Muscle size will be assessed using Ultrasonography
Measured: Changes from baseline at 7 months
Secondary outcomes (3)
Change in Quality of life score
Quality of life will be assessed using the Sort Form 36 questionnaire. The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status and is consisted of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.
The eight sections are:
- vitality
- physical functioning
- bodily pain
- general health perceptions
- physical role functioning
- emotional role functioning
- social role functioning
- mental health
Measured: Changes from baseline at 7 months
Change in Functional Capacity
Functional capacity will be assessed by the 6 min walking test
Measured: Changes from baseline at 7 months
Change in Daily Physical activity
Daily physical activity will be assessed by a 7 day recall pedometer
Measured: Changes from baseline at 7 months

- The current study is a randomized clinical trial lasting for 7 months.

Patients enrolled by a research assistant assigned into the study while the order that the patients assigned to the first scenario was randomly using a computer random number generator.

Questions about this trial
What is this clinical trial studying?
A study testing Cold Dialysis, Typical Dialysis and Exercise in people with End Stage Renal Failure on Dialysis, run by University of Thessaly at 3 sites in Greece.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Body Heat Storage (time frame: Changes from baseline at 7 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03905551, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2021.
